This was an ancient method for cultivating the soul.
It had come from the Pill Tower, handed to him by the Pill Tower's Great Elder back then. After receiving it, Liu Bai had merely glanced through it before putting it away.
After all, he had been busy absorbing Heavenly Flames at the time. Later, he had been occupied with saving Yao Lao, leaving him no time to study it properly.
Now, he finally had the time to take a good look.
Liu Bai carefully spread open the scroll, yet no words appeared upon it.
He was not surprised. Soul Power spread out from between his brows and slowly enveloped the scroll.
As Liu Bai's Soul Power covered it, invisible ripples quietly spread across the parchment. Then, streams of information invisible to the naked eye flowed along with his soul, pouring into Liu Bai's mind.
"Great Evolution Soul Art..."
The influx of information entered Liu Bai's mind and transformed into vast amounts of profound text, floating in the depths of his consciousness.
Upon reading it carefully, he found that it was indeed a cultivation art for the soul.
Liu Bai closed his eyes and pondered, carefully savoring the mysteries of this cultivation art.
This so-called Great Evolution Soul Art used one's own soul as its foundation, continuously tempering and strengthening it through a special circulation method.
Unlike ordinary soul cultivation methods, the Great Evolution Soul Art placed greater emphasis on the word "evolution."
It could continuously divide and reorganize Soul Power, allowing the soul to be tempered and elevated throughout the process of division and reorganization.
"Interesting..."
Liu Bai opened his eyes, a glint flashing through them.
With his current soul realm, ordinary soul cultivation methods were already of little use to him.
But the Great Evolution Soul Art was different.
